Almost everything. Rega P2. Creek OBH-8 phono stage. Odyssey Tempest pre- and Stratos Plus amp. Ah Tjoeb CD player. Symphonic Line Legato speakers. All purchased new around 17 years ago and working great. Also pair of Rogers LS3-5A I bought in '77. And an Audionics amp from 1980. Mostly on the side lines but sound great when I bring them out.
What’s in your system today that you also had 10 years ago?
For me, it’s only my turntable, an LP 12, though I did have a Kore installed in 2015 so it’s not quite what it was 10 years back.
